摘要： A method and apparatus for improving the image quality obtained by an imaging-based scanner comprising a housing supporting one or more protective windows. The apparatus further comprises at least one scanning arrangement, the scanning arrangement comprising illumination and imaging optics. The illumination and imaging optics form a respective field of view for imaging a target object. A light baffle is attached to the scanning arrangement. The light baffle has an aperture corresponding to each of the illumination and imaging optics such that stray light reflected from the protective windows is absorbed by the light baffle, improving the image quality of the imaging-based scanner.

摘要： A method and imaging assembly (10) are disclosed adapted for reading a target object comprising a scan engine (48) having a sensor (46), focusing optics (44), and an imager (48). The scan engine includes a field-of-view defining an area to be imaged by the imaging assembly (10). A housing (80) internally lodges the scan engine (48) and an illumination source (36). The illumination source (36) is adapted to project illumination from the housing (80). A boot (30) extends from the housing (80) for shaping the illumination as it passes through the boot to form an illumination pattern from the illumination. The illumination pattern substantially conforms to a geometrical shape of the boot (30) and is adapted to envelope the scan engine field-of-view.
